CM Punk will lose to Ryback (and Heyman)
It just does not make sense. A good guy winning against the bad at the first opportunity. That does not happen in the world of WWE.
And keeping in mind this logic, one has to assume that CM Punk will not be able to get the job done at WWE Battleground. Sure, CM Punk will be the crowd favourite and he will put up a great fight. But the ending of the match will be quite anti-climatic.
Be it anything, Heyman, Ryback or even Axel, the match will not end with a clear winner. And if it somehow does, the winner will not be CM Punk.
WWE needs this feud to go forward and make it all the way to Hell in a Cell, if not Survivor Series. Finishing the feud now, when there are two consecutive PPVs lined up, will be bad business. Also, they will not be able to involve Punk in other storylines, given the shortage of time.
So, Ryback will stand tall at the end of the match. Whether it is with, or without, Paul Heyman by his side is yet to be seen.
